Monk Build for AoE, which stat?

Im curious as to which stats i should be equiping for 4 of my 5 monks, they are Mistweaver and are merely for using spinning crane kick for healing and damageing AoE.

I dont care about upping the healing even more with intel, i just want to increase their attack power when using spinning crane kick. Any extra intel i get from stats are fine as they will only serve the purpose of increasing my mana pool.

So how does one increase the damage of skills like spinning crane kick? Agility or Strength?
